The basins are those in the North Atlantic (a), the western North Pacific (b), the eastern North Pacific (c), the Northern Indian Ocean (d), the Southern Indian Ocean (e) and the South Pacific (f). Linear trend lines are shown with their 95% two-sided confidence intervals (shaded). Note that the yaxes in e and f increase downwards.

Contributions

J.P.K. had the idea for, and designed, the study, and performed the analyses with input from K.A.E. and G.A.V. J.P.K., K.A.E. and G.A.V. provided data and participated in interpretation of the results and the writing of the manuscript.
